RESULTS CALCULATE SCAN SURFACES Scan_name

              

This command performs a scan of all the surfaces of the currently selected results attribute to find extreme values. The required results attribute in the required loadcase should therefore be selected before the command is issued.

Scan_name = The name to be given to a new scan loadcase (to contain the output attribute of the scan) or the name of an existing scan loadcase (See notes 1 and 2).

Notes:

1.

Defining a new scan loadcase
If the scan loadcase does not exist the user will first be prompted for the criterion for the scan. The choice is from the following keywords:

MAX = Scan for maximum values

MIN = Scan for minimum values

ABSMAX = Scan for absolute maximum values

ABSMIN = Scan for absolute minimum values

The user will then be prompted for a description of the scan loadcase.

2.

Using an existing scan loadcase
If the scan loadcase already exists, then the existing definition of the scan will be referenced and the user will not be prompted for anything.

To avoid confusion, an existing scan loadcase can only be added to if the currently selected loadcase (where the attribute to be scanned exists) is the same loadcase as the one that was selected when this scan loadcase was first created. If this is not the case then an error message will be produced and the scan command will be aborted.

3.

Restrictions on the results attribute(s) to be scanned
An attribute cannot be scanned if it already exists in the scan loadcase, or if it contains material independent results (which are never multi-surface), or if it contains more than ten components, or if it contains enumerative or complex components. In these cases an error message will be displayed, the scan command will be aborted and existing attribute data in the scan loadcase will not be overwritten. A warning message will be produced if the attribute being scanned has different numbers of surfaces in different places or is single surface, but the surface scan will not be aborted.

4.

Status on command completion
On successful completion of the scan surfaces command, the scan loadcase will become the current loadcase, and the results attribute and component selected prior to the scan surfaces command will remain current.

5.

Use of scan loadcases
Results stored in scan loadcases may be accessed and presented in the normal way, with the exception of RESULTS CALCULATE commands which are blocked.

6.

Use of scan loadcases with assemblies
It is not currently possible to define and perform a surface scan on an assembly model. However, any scan loadcases existing in the models used to create the assembly will exist in the assembly model, and the user should ensure that the definition of the surface scan is consistent for each model in the assembly.

Examples:

RESULTS CALCULATE SCAN SURFACES SCAN1

The following is an example prompt sequence if `SCAN1' is a new scan loadcase:

 CRITERION => MAX
 20 Character Ref => Max of all surfaces
